Can I connect external hard drive with cable to my cell phoen?

[AC Question]

Hello,

I would like to know if it is possible to connect external hard drive through OTG cable to my cell phone (Motorola Moto g 1st gen - it supports OTG).

The problem I am afraid of is that I'm not sure whether my phone can charge the external hard drive - and if it can - how much power does it usually require?

I know that there are some wireless hard drives but I would like to know if I can use the one I have.

Thank you
